Something like this?
> my.data<-data.frame("var"=c(1,2,5,"",66,4,3,"",67,5,3,2,1,4,32,56,23),
stringsAsFactors=F)
> my.data$var
[1] "1" "2" "5" "" "66" "4" "3" "" "67" "5" "3" "2" "1"
"4" "32" "56" "23"
> my.data$var[ my.data$var=="" ] <-NA
> my.data$var
[1] "1" "2" "5" NA "66" "4" "3" NA "67" "5" "3" "2" "1"
"4" "32" "56" "23"
Kind regards,
